That you may [reverently] fear the Lord your God, you and your son and your son's son, and keep all His statutes and His commandments which I command you all the days of your life, and that your days may be prolonged. Deuteronomy 6:2
You shall walk in all the ways which the Lord your God has commanded you, that you may live and that it may go well with you and that you may live long in the land which you shall possess. Deuteronomy 5:33
